Use this skill when diagnosing IAM and access failures for Bedrock and SageMaker. It traces the authorization chain — caller identity, iam:PassRole, trust policy, role permissions, resource policies, SCPs — to name the denying hop and propose a scoped policy. Read-only. Use when a Bedrock or SageMaker call fails on permissions: InvokeModel or Converse AccessDeniedException, CreateTrainingJob or CreateEndpoint AccessDenied, "is not authorized to perform…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# AI/ML Access Diagnostics Diagnose why an AI/ML service call was denied. Walk the authorization chain hop by hop, name the hop that denied the call, and propose a scoped IAM policy for human review. Read-only throughout. ## Checklist Work through these steps in order. Each is detailed in its own section below. - [ ] **Step 1 — Classify the request:** confirm the service is Bedrock or SageMaker, and that there is an observed failure (not a speculative audit). Stop otherwise. - [ ] **Step 2 — Establish identity and scope:** record the agent's own identity, extract the principal/action/resource ARNs, and flag cross-account. - [ ] **Step 3 — Collect evidence, policy reads first:** read the chain's policy documents by hand; use CloudTrail and simulation only as corroboration. - [ ] **Step 4 — Walk the chain:** traverse the six hops in precedence order; do not stop at hop 1 just because it passed. - [ ] **Step 5 — Apply service-specific knowledge:** rule out non-IAM denial causes for the service explicitly. - [ ] **Step 6 — Assign verdicts:** give every hop exactly one token from the closed verdict set. …

How to install
mdr add aws/tools-for-devops-agent/aiml-access-diagnostics@sha256:cbafd2ca2e6165d0The line at the top of this page pins the label v1.2.4, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
